ROOFING UNIT.

Original No. 1,318,238, dated October 7, 1919, Serial No. 288,035, filed April 7, 1919. Application for reissue filed October 5, 1921.

This invention relates to roofing units, for covering roofs or the like, made of sheet roofing material, which, when laid, present the appearance of shingles.

i Among other objects, the invention. is intended to provide. a novel and improved roofing unit, which, when laid on a roof, will produce a pleasing appearance.

A further ob ect is to provide a roofing l unit in which the liability of leakage is minimized.

Another object is to rovide a roofing unit of this type economicaily from sheet roofing material with-.a minimum of waste.

l The invention consists of the novel constructions, arrangements, and combinations,

to beihereinafter described and claimed, for

carryin out the above stated objects and such other objects as will appear from the 9 following description.

. The invention is illustrated in certain embodiments in the accompanying drawing in which: 1

Figure 1 is a plan view of a sheet of roofing material in which the lines, along which the various shingle units are severed, are indicated by dotted lines.

Figure 2 is a plan view illustrating the appearance of a roofing surface when laid 0 with the shingle units illustrated in Figure 1. Figure'3 is an illustration of the manner of cutting .a different formof roofing unit I from a sheet of roofing material soas to embody certain features of the invention.

5 Figure 4 illustrates the appearance of roofing when laid with the roofing unit illustrated in Figure 3. I

Like'characters of reference designate like parts in the several figures of the drawing.

0 In the drawing designates *a sheet of roofing material of limited width from which the roofing units hereinafter described "are adapted to be cut.- The individual, roofin units comprise a body or strip 11 formed 5 along one edge with a shingle tab or projecsome of semi-hexagonal s ape. The lower end 13-of the shingle tab-is considerably longer than the sides 14.- Adjacent the tab is a recess 15 which corresponds exactly in 0 size and sha to the shingle tab, but reversed in position. The illustration unit 11 comprises a pair of shingle tabs having renames or spaces 15 between them.-

Serial No. 505,634.

It will be noted from Figure 1 that the shingle tabs along the edge of one unit are complementary to the spaces or recesses of the adjacent unit and, therefore, the spaces between adjacent tabs in each unit are in effect complementary to such tabs. In other words, the material occupying the spaces or recesses on one unit form the shingle tabs on the adjacent unit. Thus the shingle units may be out without substantial waste of material. If desired, as illustrated in Figure 1, a sheet of material 10 wide enough to form a pair of units 11 may be employed. The sheet is then severed along the lines'lfi to divide the strip cut from the sheet into two units. -Preferably, the lines 16 along which the units are severed are ofiset slightly so 70 as not to be extensions of the side of the corresponding shingle tab. Between each pair of units, the sheet is severed alongthe straight line 17 as shown in Figure 1.

As shown in Figure '1 the various units are cut diagonally of or on the bias of the sheet 10 with one side 14 ofa shingle tab parallel and substantially coinciding with one edge of the sheet 10. This arrangement not only saves material in cutting the roofing unit having semihexagonal tabs but also provides a unit having ends 18 inclined to the general direction of the length of the unit for the purposeof providing joints 19 between adjacent units which are 'notat right angles to the courses of units when laid in the roof. Preferably the units are made with an equal number of tabs andspaces or recesses, so that when laid in courses with the. ends at one unit abutting the ends of adjacent units, the tabs will be separated-by eiual spaces. Preferabl the width or de th- 0 the unit-11 is consi erably greater t an the depth of the shingle tab 'so that when laid in a roof'a greater number of thick' 0 nesses of roofing material will be provided. In the illustrative shingle unit, the depth of the body of the strip is substantially twice the depth of the shingle tab and thus rovidesa roofing which is covered by at east 100 two thicknesses of roofing material at every point.

As illustrated in Figure 2, the units are adapted to be laid on a roof in courses with v the ends of the tabs 'of one course coinciding with the bases of the recesses or spaces between adjacent tabs of the next lower course of units, thus presenting the appearance of courses of conventional hexagonal shingles. The oblique lines of juncture 19 between adjacent units in each course are covered by intact portions of the units of both of the overlying courses.

In Figure 3 is illustrated the manner of cutting a different form of shingle unit, bias of the sheet of material. The units 20 have rectangular-shaped tabs with. narrow spaces 22 between them. The ends 23 of the units 20 are inclined to the front edge of the unit. As shown in Figure 3 the sheet of roofing material is made wide enough to form two units, cut from the material side by side. These units are formed by cutting a series of ually spaced slots 24 in the material to provide the spaces 22 in theunits and by severing the sheet along the lines 25 and 26 bias to the sheet. The diagonal strips are severe-d along the staggered lines 27 to di vide each transverse strip into a pair. of units.

of a roof covering-employing the units 20. It will be noted that the units 20 are so cut from the sheet that the ends of the unit-lie at a space or notch 22. The oblique lines of juncture 28 between adjacent un1ts of each course are covered by intact portions of the units of both of the overlyin courses. This result is effected by staggering the notches or spaces 22 between the' tabs in adjacent courses.-.
